What is the solution for y in the equation y^2 = 64? What the solution to the equation (x - 2)(x - 4) = 8? What is the solution to the equation 4x - 6 + 2x = 18? What is the solution to the equation 5x + 15 + 2x = 24 +...
Sincet=cos2x, it must be in the range(0,1): - Fort=a+3: 0≤a+3≤1 This simplifies to: −3≤a≤−2 - Fort=−1: This is not possible sincecos2xcannot be negative. Conclusion Thus, the values ofafor which the equation has solutions are: ...
The basic aspect of an equation is that equality is satisfied. This is precisely the essence of an equation: Finding the value or values of the unknown for which the equation is satisfied. Answer and Explanation: Since we have equality, we can work the terms o...
aRecall that there were cases of the equation x2+ c = bx which had no solutions. Do all cases of the equation x2+ bx = c have solutions, where we are always assuming that b and c are positive numbers? 召回有等式x2+的案件没有解答的c = bx。 在哪里等式x2+ bx = c的所有案件有...
